This manual is intended for the following personnel, who must also have knowledge of electrical sys-

tems (an electrical engineer or the equivalent).

•Personnel in charge of installing FA systems

•Personnel in charge of designing FA systems

•Personnel in charge of managing FA systems and facilities

zCP-series CP2E CPU Units

•Essential Model CP2E-ED-

A model of CPU Unit that supports connections to Programmable Terminals and basic control

applications using instructions such as basic, movement, arithmetic, and comparison instructions.

•Standard Model CP2E-SD-

A model of CPU Unit that supports connections to inverters and servo drives.

•Network Model CP2E-ND-

Terms and Conditions Agreement

zExclusive Warranty

Omron’s exclusive warranty is that the Products will be free from defects in materials and workman-

ship for a period of twelve months from the date of sale by Omron (or such other period expressed in

writing by Omron). Omron disclaims all other warranties, express or implied.

zLimitations

OMRON MAKES NO WARRANTY OR REPRESENTATION, EXPRESS OR IMPLIED, ABOUT

NON-INFRINGEMENT, MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE OF

THE PRODUCTS. BUYER ACKNOWLEDGES THAT IT ALONE HAS DETERMINED THAT THE

PRODUCTS WILL SUITABLY MEET THE REQUIREMENTS OF THEIR INTENDED USE.

Omron further disclaims all warranties and responsibility of any type for claims or expenses based

on infringement by the Products or otherwise of any intellectual property right.

zBuyer Remedy

Omron’s sole obligation hereunder shall be, at Omron’s election, to (i) replace (in the form originally

shipped with Buyer responsible for labor charges for removal or replacement thereof) the non-com-

plying Product, (ii) repair the non-complying Product, or (iii) repay or credit Buyer an amount equal

to the purchase price of the non-complying Product; provided that in no event shall Omron be

responsible for warranty, repair, indemnity or any other claims or expenses regarding the Products

unless Omron’s analysis confirms that the Products were properly handled, stored, installed and

maintained and not subject to contamination, abuse, misuse or inappropriate modification. Return of

any Products by Buyer must be approved in writing by Omron before shipment. Omron Companies

shall not be liable for the suitability or unsuitability or the results from the use of Products in combi-

nation with any electrical or electronic components, circuits, system assemblies or any other materi-

als or substances or environments. Any advice, recommendations or information given orally or in

writing, are not to be construed as an amendment or addition to the above warranty.

See http://www.omron.com/global/ or contact your Omron representative for published information.

OMRON COMPANIES SHALL NOT BE LIABLE FOR SPECIAL, INDIRECT, INCIDENTAL, OR CON-

SEQUENTIAL DAMAGES, LOSS OF PROFITS OR PRODUCTION OR COMMERCIAL LOSS IN ANY

WAY CONNECTED WITH THE PRODUCTS, WHETHER SUCH CLAIM IS BASED IN CONTRACT,

16 CP2E CPU Unit Software User’s Manual(W614)

Omron Companies shall not be responsible for conformity with any standards, codes or regulations

which apply to the combination of the Product in the Buyer’s application or use of the Product. At

Buyer’s request, Omron will provide applicable third party certification documents identifying ratings

and limitations of use which apply to the Product. This information by itself is not sufficient for a com-

plete determination of the suitability of the Product in combination with the end product, machine, sys-

tem, or other application or use. Buyer shall be solely responsible for determining appropriateness of

the particular Product with respect to Buyer’s application, product or system. Buyer shall take applica-

tion responsibility in all cases.

NEVER USE THE PRODUCT FOR AN APPLICATION INVOLVING SERIOUS RISK TO LIFE OR

PROPERTY OR IN LARGE QUANTITIES WITHOUT ENSURING THAT THE SYSTEM AS A WHOLE

HAS BEEN DESIGNED TO ADDRESS THE RISKS, AND THAT THE OMRON PRODUCT(S) IS

PROPERLY RATED AND INSTALLED FOR THE INTENDED USE WITHIN THE OVERALL EQUIP-

MENT OR SYSTEM.

Omron Companies shall not be responsible for the user’s programming of a programmable Product, or

any consequence thereof.

Data presented in Omron Company websites, catalogs and other materials is provided as a guide for

the user in determining suitability and does not constitute a warranty. It may represent the result of

Omron’s test conditions, and the user must correlate it to actual application requirements. Actual perfor-

mance is subject to the Omron’s Warranty and Limitations of Liability.

Product specifications and accessories may be changed at any time based on improvements and other

reasons. It is our practice to change part numbers when published ratings or features are changed, or

when significant construction changes are made. However, some specifications of the Product may be

changed without any notice. When in doubt, special part numbers may be assigned to fix or establish

key specifications for your application. Please consult with your Omron’s representative at any time to

confirm actual specifications of purchased Product.

Information presented by Omron Companies has been checked and is believed to be accurate; how-

ever, no responsibility is assumed for clerical, typographical or proofreading errors or omissions.
